/**
 * @brief SLSphere creates a sphere mesh based on SLSpheric w. 180 deg polar angle.
 * @remarks It is important that during instantiation NO OpenGL functions (gl*) 
 * get called because this constructor will be most probably called in a parallel 
 * thread from within an SLScene::registerAssetsToLoad or SLScene::assemble 
 * function. All objects that get rendered have to do their OpenGL initialization 
 * when they are used the first time during rendering in the main thread.
 * For this mesh it means that the objects for OpenGL drawing (_vao, _vaoP,
 * _vaoN, _vaoT and _vaoS) remain unused until the first frame is rendered.
